Description

Technical Field

[0001] This application relates to the field of energy-saving technology, and in particular to a cooling device, method, system, and data center. Background Technology

[0002] Cooling towers, as highly efficient cooling devices, are widely used in air conditioning systems in industrial, civil, and data center applications. They utilize the evaporation of coolant to dissipate heat and the heat exchange between the coolant and air to reduce the coolant temperature. However, the heat and mass transfer performance varies significantly at different locations within a cooling tower, resulting in insufficient overall heat exchange efficiency. Summary of the Invention

[0003] Embodiments of this application provide a cooling device, method, system, and data center for improving the heat exchange capacity and efficiency of the cooling device.

[0004] To achieve the above objectives, the embodiments of this application adopt the following technical solutions:

[0005] In a first aspect, a cooling device is provided, comprising: a tower body; a liquid inlet channel disposed on the tower body; and a first liquid distributor, a first packing, at least one liquid distribution assembly, and a second packing disposed inside the tower body; wherein the first liquid distributor is connected to the liquid inlet channel; the first packing is disposed below the first liquid distributor; at least one first liquid distribution assembly is disposed below the first packing; and the second packing is disposed below the at least one first liquid distribution assembly; wherein the first liquid distribution assembly is used to collect liquid flowing through the first packing and spray the liquid onto the second packing.

[0006] In this embodiment, the first liquid distributor can uniformly spray liquid into the first packing material. The liquid exchanges heat with the air in the first packing material, and the liquid temperature gradually decreases. After passing through the first packing material, part of the liquid falls directly into the second packing material, and the other part falls into the liquid distribution assembly. The liquid distribution assembly can uniformly spray the collected liquid into the second packing material. Thus, the liquid undergoes secondary heat exchange with the air in the second packing material, further reducing its temperature. Therefore, in this embodiment, the heat dissipation capacity of the cooling device is improved by setting multiple layers of packing material. Under the same heat dissipation conditions, compared with a cooling device with only one layer of packing material, the cooling device provided in this embodiment has improved heat dissipation efficiency, and at the same time, the cooling device occupies a smaller area.

[0007] In some optional embodiments, there are multiple first liquid distribution assemblies, which are arranged at intervals in a first direction; the first direction is perpendicular to the arrangement direction of the first packing and the second packing.

[0008] In some alternative embodiments, the liquid distribution assembly includes: a water collection element and at least one second liquid distributor; the water collection element is disposed below the first packing material; and at least one second liquid distributor is disposed below the water collection element and connected to the water collection element.

[0009] In some alternative embodiments, the water collecting device is provided with a groove, the opening of which faces the first packing material; the second liquid distributor communicates with the groove.

[0010] In some optional embodiments, the water collecting component includes a first water collecting plate, a first connecting plate, and a second water collecting plate, with the first connecting plate connected between the first water collecting plate and the second water collecting plate; the end of the first water collecting plate away from the first connecting plate and the end of the second water collecting plate away from the first connecting plate both extend toward the first filler, and the first water collecting plate, the first connecting plate, and the second water collecting plate form a groove.

[0011] In some alternative embodiments, the opening of the groove along the second direction is larger than the bottom of the groove along the first direction; the second direction is parallel to the arrangement direction of the first water collecting plate, the first connecting plate, and the second water collecting plate. Thus, by providing a larger opening to collect more liquid and a smaller bottom to gather the collected liquid together, coolant loss is reduced.

[0012] In some alternative embodiments, the cooling device further includes at least one first water-blocking element disposed between the first packing and at least one first liquid distribution assembly; the edge portion of the first water-blocking element is inclined toward the first liquid distribution assembly.

[0013] Therefore, after passing through the first packing material, part of the liquid falls directly into the liquid distribution assembly, while the other part falls onto the water-blocking component and is then guided into the liquid distribution assembly by the water-blocking component. This increases the amount of liquid collected by the liquid distribution assembly and improves the heat exchange capacity of the cooling device.

[0014] In some optional embodiments, the first water-blocking component includes a first guide plate and a second guide plate; the first guide plate and the second guide plate are respectively inclined toward the slots of two adjacent water collecting components, and the edges of the first guide plate and the second guide plate are respectively located above the slots of two adjacent water collecting components.

[0015] In some alternative embodiments, the first water-blocking component further includes a second connecting plate connected between the first guide plate and the second guide plate.

[0016] In some optional embodiments, there are multiple first water-blocking components, and multiple first water-blocking components and multiple water-collecting components are arranged alternately in the upper and lower parts, and there is a gap between the water-blocking components and the water-collecting components in the third direction; the third direction is the arrangement direction of the first packing and the second packing.

[0017] In some optional embodiments, the cooling device further includes: an air inlet channel and an air outlet channel disposed on the tower body; the air inlet channel is disposed below the second packing; and the air outlet channel is disposed above the first liquid distributor. Thus, the air inlet and air outlet channels promote airflow and improve heat exchange efficiency.

[0018] In some alternative embodiments, the cooling device further includes: a third packing material disposed inside the tower body; the third packing material being disposed below the second packing material and above the air inlet passage; at least one second liquid distribution assembly disposed between the second packing material and the third packing material; the second liquid distribution assembly being used to collect liquid flowing through the second packing material and spray the liquid onto the third packing material.

[0019] In some alternative embodiments, the cooling device further includes at least one second water-blocking element disposed between the third packing and at least one second liquid distribution assembly; the edge portion of the second water-blocking element is inclined toward the second liquid distribution assembly.

[0020] In some alternative embodiments, the cooling device further includes a liquid outlet channel located at the bottom of the tower body. This allows the cooled liquid to be discharged outside the tower body through the liquid outlet channel.

[0021] In a second aspect, a cooling method is provided, comprising: a first liquid distributor spraying liquid flowing into the first liquid distributor into a first packing, such that the liquid exchanges heat with gas in the first packing and then falls into a second packing and / or a first liquid distribution assembly, wherein gas flows from one end of the tower body near the second packing to the other end of the tower body near the first packing; and the first liquid distribution assembly spraying the collected liquid into the second packing, such that the liquid exchanges heat with gas in the second packing.

[0022] Thirdly, a cooling system is provided, the cooling device comprising: a cooling pump, and the cooling device provided in the first aspect, wherein the cooling pump is connected to the liquid inlet channel of the cooling device.

[0023] Fourthly, a data center is provided, comprising: servers, and a cooling system provided in the third aspect, the cooling system being used to reduce the temperature of the servers.

[0024] The technical effects of any of the possible implementations of the second to fourth aspects can be found in the technical effects of the different implementations of the first aspect mentioned above, and will not be repeated here. Attached Figure Description

[0037] With the rapid development of data centers, the requirements for construction cycles are becoming shorter and shorter, and the requirements for energy efficiency are also becoming higher. Data centers house a large number of server racks, and servers 300, operating continuously, generate a significant amount of heat. To ensure the normal operation of servers 300, a cooling system 200 is needed to cool them down.

[0038] The implementation of the technical solution of this application will be further described in detail below with reference to the accompanying drawings.

[0039] See Figure 1 , Figure 1 This is a schematic diagram illustrating an application scenario of the cooling system 200 provided in this application. For example... Figure 1 As shown, the cooling system 200 includes a cooling device 100 and a cooling pump 201.

[0040] Cooling pump 201 is used to drive the coolant to circulate between cooling unit 100 and server 300. The coolant can exchange heat with server 300, thereby reducing the temperature of server 300 and increasing the temperature of coolant.

[0041] The cooling device 100 utilizes the evaporation of the coolant to dissipate heat and the heat exchange when the coolant comes into contact with the air to reduce the coolant temperature.

[0042] However, the cooling capacity of the coolant is limited, so in some alternative embodiments, the cooling system 200 also includes a chiller 202, a heat exchanger 203, a chilled pump 204 and an air conditioner 205 disposed between the cooling pump 201 and the server 300.

[0043] The chiller unit 202 is used to generate refrigerant through a vapor compression refrigeration cycle and supply it to the air conditioner 205 for cooling. The chiller unit 202 can also be called a water-cooled chiller unit.

[0044] The chilled water pump 204 is used to deliver the refrigerant produced by the chiller unit 202 to the air conditioner so that the air conditioner can perform cooling. As a result, the temperature of the server 300 decreases under the action of the air conditioner 205, but at the same time the temperature of the refrigerant increases.

[0045] The chilled water pump 204 is also used to drive the heated refrigerant into the heat exchanger 203. That is, the refrigerant circulates between the chiller 202, the air conditioner 205 and the heat exchanger 203 under the drive of the chilled water pump.

[0046] Heat exchanger 203 is used to exchange heat between the refrigerant and the coolant, thereby lowering the refrigerant temperature and raising the coolant temperature. For example, heat exchanger 203 can be a plate heat exchanger.

[0047] Cooling pump 201 is used to drive coolant to circulate in cooling device 100 and heat exchanger 203.

[0048] The cooling device 100 utilizes the evaporation of coolant to dissipate heat and the heat exchange between the coolant and air to reduce the coolant temperature. However, the heat and mass transfer performance varies significantly at different locations within the cooling device 100, resulting in insufficient overall heat exchange efficiency.

[0049] Therefore, embodiments of this application also provide a cooling device. For example... Figure 2As shown, the cooling device includes: a tower body 101; a liquid inlet channel 102 disposed on the tower body 101; and a first liquid distributor 103, a first packing 104, at least one first liquid distribution assembly 105, and a second packing 106 disposed inside the tower body 101; wherein, the first liquid distributor 103 is connected to the liquid inlet channel 102; the first packing 104 is disposed below the first liquid distributor 103; the first liquid distribution assembly 105 is disposed below the first packing 104; and the second packing 106 is disposed below at least one first liquid distribution assembly 105. The first liquid distribution assembly 105 is used to collect the liquid flowing through the first packing 104 and spray the liquid onto the second packing 106.

[0050] In this embodiment, the first liquid distributor 103 can uniformly spray liquid into the first packing 104. The liquid exchanges heat with the air in the first packing 104, and the liquid temperature gradually decreases. After passing through the first packing 104, part of the liquid falls directly into the second packing 106, and the other part falls into the first liquid distribution assembly 105. The first liquid distribution assembly 105 can uniformly spray the collected liquid into the second packing 106. Thus, the liquid undergoes secondary heat exchange with the air in the second packing 106, further reducing the temperature. Therefore, in this embodiment, the heat dissipation capacity of the cooling device is improved by setting multiple layers of packing. Under the same heat dissipation conditions, compared with a cooling device with only one layer of packing, the cooling device provided in this embodiment has improved heat dissipation efficiency, and at the same time, the cooling device occupies a smaller area.

[0051] This application also provides a cooling device. See [link to relevant documentation]. Figure 3 The schematic diagram of the cooling device shown includes: a tower body 101; a liquid inlet channel 102 disposed on the tower body 101; and a first liquid distributor 103, a first packing 104, at least one first water baffle 107, at least one first liquid distribution assembly 105, and a second packing 106 disposed inside the tower body 101.

[0052] The first liquid distributor 103 is connected to the liquid inlet channel 102; the first packing 104 is disposed below the first liquid distributor 103; at least one first water-blocking component is disposed below the first packing 104; at least one first liquid distribution assembly 105 is disposed below at least one first water-blocking component 107; and the second packing 106 is disposed below at least one first liquid distribution assembly 105.

[0053] The following is about Figure 3 The various parts of the cooling device 100 shown will be described in detail.

[0054] The first liquid distributor 103 is used to uniformly spray the liquid flowing through the liquid inlet channel 102 into the first packing 104. For example, the liquid can be a coolant. The first liquid distributor 103 includes a distribution pipe and multiple nozzles 1031 connected to the distribution pipe. The distribution pipe is connected to the liquid inlet channel 102 to allow the liquid to enter the tower body 101. The multiple nozzles 1031 are evenly distributed above the first packing 104 to improve the wettability and wetting area of ​​the coolant in the first packing 104, thereby improving the cooling effect of the first packing 104.

[0055] It should be noted that the embodiments of this application do not limit the position of each nozzle 1031. Multiple nozzles 1031 can be arranged on the same reference plane, for example, the reference plane is parallel to the upper surface of the first packing 104. They can also be arranged on different reference planes, that is, the distances between multiple nozzles 1031 and the upper surface of the first packing 104 are different. For example, the distance between some nozzles 1031 and the first packing 104 can be a first distance value, and the distance between other nozzles 1031 and the first packing 104 can be a second distance value, where the first distance value and the second distance value are different. Those skilled in the art can set the first distributor 103 according to the spraying requirements, and the embodiments of this application do not impose any limitations.

[0056] The first packing material 104 is used to increase the contact area between the liquid and air, and prolong the contact time. The first packing material 104 has channels, allowing the liquid sprayed by the first distributor 103 to flow slowly down along these channels. During this flow, the liquid exchanges heat with the air, causing its temperature to drop.

[0057] In some optional embodiments, the first packing 104 includes a plurality of corrugated packing diaphragms 1041 arranged at intervals; each corrugated packing diaphragm 1041 has S-shaped grooves 1042 and protrusions 1043 arranged at intervals, with the top of the protrusion 1043 of each corrugated packing diaphragm 1041 connected to the bottom of its adjacent groove 1042, thereby forming an S-shaped corrugated packing diaphragm 1041, and an S-shaped channel is formed between any two adjacent corrugated packing diaphragms 1041. The cross-section of the groove 1042 or the protrusion 1043 is a broken line shape or a trapezoidal shape.

[0058] In this embodiment, the coolant flows slowly down the S-shaped channels in the first packing 104, and exchanges heat with the air during the downward flow to reduce the temperature of the coolant. The shape of the S-shaped channels can effectively enhance the disturbance effect of the airflow and liquid flow within the channels, thereby increasing the gas-liquid heat exchange area and significantly improving the heat transfer efficiency between the airflow, liquid flow and packing.

[0059] It is understood that the above examples are merely examples listed to better understand the technical solutions of the embodiments of this application, and are not intended to be the only limitation on the embodiments of this application. In addition to the first packing 104 with an S-shaped cross-section described above, other types of first packing 104 may be used in some other embodiments of the cooling device, such as a first packing 104 with a honeycomb cross-section. The embodiments of this application do not impose any limitations.

[0060] However, considering that the coolant becomes unevenly distributed in the first packing 104 as it flows downwards, this leads to a decrease in the heat exchange effect of the cooling device. Under the same heat dissipation conditions, the larger the temperature difference, the smaller the coolant flow rate, which in turn leads to a decrease in the coolant spray density. The wettability and heat and mass transfer performance of the first packing 104 at different heights will further decrease. Therefore, the heat exchange effect of a single liquid distribution will be worse in scenarios with large temperature differences (e.g., the temperature difference of the liquid before and after entering the cooling device exceeds 12°C) compared to scenarios with small temperature differences.

[0061] In view of this, the cooling device 100 in this embodiment of the application is further provided with a first liquid distribution assembly 105 below the first packing 104. Thus, after the coolant flows through the first packing 104, a portion will fall directly into the second packing 106, while the other portion will fall into the first liquid distribution assembly 105. The first liquid distribution assembly 105 sprays the collected coolant onto the second packing 106.

[0062] It should be noted that the embodiments of this application do not limit the number of first liquid distribution assemblies 105. There may be one or more first liquid distribution assemblies 105.

[0063] In some optional embodiments, the cooling device 100 may include only one first liquid distribution assembly 105, which may include a water collection element 1051 and a plurality of second liquid distributors 1052. The water collection element 1051 is disposed below the first packing 104 and is used to collect the coolant flowing through the first packing 104. The plurality of second liquid distributors 1052 are disposed below the water collection element 1051 and communicate with the water collection element 1051. Each second liquid distributor 1052 is used to uniformly spray the coolant collected by the water collection element 1051 into the second packing 106, so as to improve the wettability and wetting area of ​​the coolant in the second packing 106, thereby increasing the liquid distribution effect of the second packing 106.

[0064] In some specific embodiments, the water collecting component 1051 is provided with a groove, the opening of which faces the first packing 104, so that at least part of the coolant falls into the groove after passing through the first packing 104.

[0065] For example, such as Figure 4As shown, the water collection component 1051 includes a first water collection plate 10511, a second water collection plate 10512, a third water collection plate 10513, a fourth water collection plate 10514, and a first connecting plate 10515. The first water collection plate 10511, the second water collection plate 10512, the third water collection plate 10513, and the fourth water collection plate 10514 are arranged around the first connecting plate 10515. The first water collecting plate 10511 and the second water collecting plate 10512 are arranged opposite to each other, and the third water collecting plate 10513 and the fourth water collecting plate 10514 are arranged opposite to each other. The ends of the first water collecting plate 10511, the second water collecting plate 10512, the third water collecting plate 10513, and the fourth water collecting plate 10514 that are away from the first connecting plate 10515 all extend towards the first packing material 104. Thus, the first water collecting plate 10511, the second water collecting plate 10512, the third water collecting plate 10513, and the fourth water collecting plate 10514 constitute the sidewalls of the groove. The first connecting plate 10515 is connected between the first water collection plate 10511 and the second water collection plate 10512. At the same time, the first connecting plate 10515 is also connected between the third water collection plate 10513 and the fourth water collection plate 10514, thereby forming the bottom of the groove.

[0066] In some specific embodiments, the opening of the groove along the second direction is larger than the bottom of the groove along the second direction, which is parallel to the arrangement direction of the first water collecting plate 10511, the first connecting plate 10515, and the second water collecting plate 10512. The larger opening facilitates the collection of more liquid, while the smaller bottom facilitates the aggregation of the collected liquid, thereby reducing coolant loss.

[0067] For example, the third water collecting plate 10513 and the fourth water collecting plate 10514 can be trapezoidal water collecting plates. In this trapezoidal water collecting plate, the lower base with the longer side can serve as the edge of the groove, and the upper base with the shorter side connects to the first connecting plate 10515, thus forming a groove whose opening dimension along the second direction is larger than the groove bottom dimension along the second direction. In this way, the included angles between the first water collecting plate 10511 and the second water collecting plate 10512 and the first connecting plate 10515 are both greater than 90 degrees, which facilitates the flow of liquid from the first water collecting plate 10511 or the second water collecting plate 10512 to the first connecting plate 10515 for collection.

[0068] In some specific examples, a plurality of drainage holes are provided in the first connecting plate 10515, through which coolant can flow from the water collector 1051 to the second distributor 1052.

[0069] It is understood that in the embodiments of this application, the second direction is understood as parallel to the arrangement direction of the first water collection plate 10511, the first connecting plate 10515, and the second water collection plate 10512. Herein, "parallel" includes the described situation and situations similar to the described situation, where the range of similarity is within an acceptable deviation range, which is determined by those skilled in the art taking into account the measurement under discussion and the errors associated with the measurement of a particular quantity (i.e., the limitations of the measurement system). For example, "parallel" includes absolute parallelism and approximate parallelism, where the acceptable deviation range for approximate parallelism can be, for example, a deviation within 5°.

[0070] In some alternative embodiments, such as Figure 5 As shown, the cooling device 100 is provided with a plurality of first liquid distribution assemblies 105, which are arranged at intervals in a first direction. Each first liquid distribution assembly 105 includes a water collection element 1051 and at least one second liquid distributor 1052. The first direction is perpendicular to the arrangement direction of the first packing 104 and the second packing 106.

[0071] See Figure 6 The diagram shows the structure of the first liquid distribution assembly. The cooling device 100 is provided with a first liquid distribution assembly 105-1, a first liquid distribution assembly 105-2, and a first liquid distribution assembly 105-3. There is a gap in a first direction between the first liquid distribution assembly 105-1, the first liquid distribution assembly 105-2, and the first liquid distribution assembly 105-3. The first liquid distribution assembly 105-1 includes a water collection component 1051-1 and a second liquid distributor 1052-1. The second liquid distributor 1052-1 is disposed below and connected to the water collection component 1051-1. The first liquid distribution assembly 105-2 includes a water collection component 1051-2 and a second liquid distributor 1052-2. The second liquid distributor 1052-2 is disposed below and connected to the water collection component 1051-2. The first liquid distribution assembly 105-3 includes a water collection component 1051-3, a second liquid distributor 1052-3, and a second liquid distributor 1052-4. The second liquid distributor 1052-3 and the second liquid distributor 1052-4 are disposed below and connected to the water collection component 1051-3.

[0072] In this embodiment, by setting up multiple first liquid distribution assemblies 105 and leaving gaps between them, the resistance encountered by the airflow can be reduced, which is more conducive to heat exchange between the coolant and the air. At the same time, setting up multiple first liquid distribution assemblies 105 can improve the uniformity and flexibility of secondary liquid distribution, thereby further improving the heat exchange efficiency of the cooling device.

[0073] It should be noted that "vertical" includes the described situation and situations similar to the described situation, where the range of similar situations is within an acceptable deviation range, which is determined by those skilled in the art taking into account the measurement under discussion and the error associated with the measurement of a particular quantity (i.e., the limitations of the measurement system). For example, "vertical" includes absolute verticality and approximate verticality, where the acceptable deviation range for approximate verticality can also be, for example, within 5°.

[0074] The water collecting element 1051 in this application embodiment is not limited to the structure provided in the above embodiment. In other examples, the water collecting element 1051 can also be other structures, such as the water collecting element 1051 being cylindrical or other shapes with water collecting function.

[0075] To further improve the heat exchange capacity of the cooling device, see Figure 5 The cooling device 100 also provides a first water-blocking member 107 between the first filler 104 and the first liquid distribution assembly 105. The edge portion of the first water-blocking member 107 is inclined toward the water collection member 1051 so as to guide the liquid into the liquid distribution device.

[0076] In some specific embodiments, there are multiple first water-blocking components 107, and multiple first water-blocking components 107 and multiple water-collecting components 1051 are arranged alternately in the upper and lower positions. There is a gap between the first water-blocking components 107 and the water-collecting components 1051 in the third direction, which is the arrangement direction of the first packing 104 and the second packing 106.

[0077] In this embodiment, by setting multiple first water-blocking components 107, and having a gap between the first water-blocking component 107 and the water-collecting component 1051 in the third direction, it is ensured that the air can be turned when passing through the first water-blocking component 107, so as to continue flowing towards the first packing 104.

[0078] In one specific embodiment, each of the first water-blocking components 107 includes a first guide plate 1071 and a second guide plate 1072; the first guide plate 1071 and the second guide plate 1072 are respectively inclined toward the slots of two adjacent water collecting components 1051, and the edges of the first guide plate 1071 and the second guide plate 1072 are respectively located above the slots of two adjacent water collecting components 1051.

[0079] Specifically, for example Figure 7 The cooling device 100 shown includes a first liquid distribution assembly 105-1, a first liquid distribution assembly 105-2, a first liquid distribution assembly 105-3, a first water-blocking component 107-1, and a first water-blocking component 107-2.

[0080] The first liquid distribution assembly 105-1 includes: a water collection component 1051-1 and a second liquid distributor 1052-1; the second liquid distributor 1052-1 is disposed below and connected to the water collection component 1051-1; the first liquid distribution assembly 105-2 includes: a water collection component 1051-2 and a second liquid distributor 1052-2; the second liquid distributor 1052-2 is disposed below and connected to the water collection component 1051-2; the first liquid distribution assembly 105-3 includes: a water collection component 1051-3 and a second liquid distributor 1052-3; the second liquid distributor 1052-3 is disposed below and connected to the water collection component 1051-3.

[0081] The first water-blocking component 107-1 includes a first guide plate 1071-1 and a second guide plate 1072-1. The first guide plate 1071-1 is inclined toward the slot of the water collecting component 1051-1, and the edge of the first guide plate 1071-1 is located above the slot of the water collecting component 1051-1. The second guide plate 1072-1 is inclined toward the slot of the water collecting component 1051-2, and the edge of the second guide plate 1072-1 is located above the slot of the water collecting component 1051-2. The first water-blocking component 107-2 includes a first guide plate 1071-2 and a second guide plate 1072-2. The first guide plate 1071-2 is inclined toward the slot of the water collecting component 1051-2, and the edge of the first guide plate 1071-2 is located above the slot of the water collecting component 1051-2. The second guide plate 1072-2 is inclined toward the slot of the water collecting component 1051-3, and the edge of the second guide plate 1072-2 is located above the slot of the water collecting component 1051-3.

[0082] Therefore, by providing a first water-blocking element 107 above the gaps between the multiple first liquid distribution assemblies 105, a portion of the coolant, after passing through the first packing 104, will fall directly into the water collection element 1051 within the first liquid distribution assembly 105. The remaining portion will be blocked by the first water-blocking element 107 and, guided by it, will also flow into the water collection element 1051. This prevents the coolant from falling directly into the second packing 106, thereby improving the liquid distribution capacity of the first liquid distribution assembly 105 and further enhancing the heat dissipation capacity and efficiency of the cooling device.

[0083] In some alternative embodiments, the first water-blocking member 107 further includes a second connecting plate connected between the first guide plate 1071 and the second guide plate 1072.

[0084] For example, such as Figure 8As shown, the first water-blocking component 107-1 includes a first guide plate 1071-1, a second guide plate 1072-1, and a first connecting plate 1073-1. The first connecting plate 1073-1 is located above the gap between the water collecting components 1051-1 and 1051-2. The first guide plate 1071-1 is inclined toward the slot of the water collecting component 1051-1, and the second guide plate 1072-1 is inclined toward the slot of the water collecting component 1051-2. The first water-blocking component 107-2 includes a first guide plate 1071-2, a second guide plate 1072-2, and a first connecting plate 1073-2. The first connecting plate 1073-2 is located above the gap between the water collecting component 1051-2 and the water collecting component 1051-3. The first guide plate 1071-2 is inclined toward the slot of the water collecting component 1051-2, and the second guide plate 1072-2 is inclined toward the slot of the water collecting component 1051-3.

[0085] In this way, after passing through the first packing 104, a portion of the coolant will fall directly into the water collection component 1051 in the first fluid distribution assembly 105. The other portion will be blocked by the first connecting plate and guided by the first guide plate 1071 or the second guide plate 1072, also flowing into the water collection component 1051. This prevents the coolant from falling directly into the second packing 106, thereby improving the fluid distribution capacity of the first fluid distribution assembly 105.

[0086] The second packing 106 is used for secondary heat dissipation of the coolant. After secondary distribution by the first liquid distribution assembly 105, the coolant falls into the second packing 106 and flows towards the bottom of the tower body 101 along the channels in the second packing 106. During the flow, the coolant exchanges heat with the air to further reduce the temperature. Compared with a cooling device with only one layer of packing, in the cooling device provided in this embodiment, under the action of the first liquid distribution assembly 105, the coolant distribution in the second packing 106 is more uniform, the wettability of the second packing 106 is higher, and the area of ​​the wetted second packing 106 is larger, thus the heat exchange efficiency of this cooling device is also higher.

[0087] Since the second packing 106 provided in this embodiment works on the same principle and plays a similar role as the first packing 104 provided in the above embodiment, the structure of the first packing 104 provided in the previous embodiment is also applicable to the second packing 106, and will not be described in detail in this embodiment. In addition, the structure of the second packing 106 in this embodiment can be the same as or different from the structure of the first packing 104. For example, both the first packing 104 and the second packing 106 can be packings with an S-shaped cross-section, or they can be packings with different structures. For example, a packing with an S-shaped cross-section can be used as the first packing 104, and a packing with a honeycomb cross-section can be used as the second packing 106.

[0088] In some alternative embodiments, such as Figure 9 As shown, the cooling device 100 further includes an air inlet channel 108 and an air outlet channel 109 disposed on the tower body 101; the air inlet channel 108 is disposed below the second packing 106; and the air outlet channel 109 is disposed above the first liquid distributor 103.

[0089] For example, refer to Figure 9 The schematic diagram of the cooling device 100 shown illustrates that the air inlet channel 108 is located at the bottom of the tower body 101 and communicates with the outside, allowing gas to enter the tower body 101. The air outlet channel 109 is located at the top of the tower body 101 and communicates with the outside, allowing gas to be discharged from the tower body 101 into the atmosphere. A fan 1091 is also provided between the air outlet channel 109 and the first liquid distributor 103. The fan 1091 helps to drive outside air through the air inlet channel into the tower body 101, and then flows upward from the bottom of the tower body, passing sequentially through the second packing 106, the first liquid distribution assembly 105, the first water baffle 107, the first packing 104, and the first liquid distributor 103, before being discharged outside the tower body 101 through the air outlet channel.

[0090] In some alternative embodiments, such as Figure 10 As shown, the cooling device 100 also includes a liquid outlet channel 110, which is located at the bottom of the tower body 101, for example, below the air inlet channel 108. A water collection tray can also be installed at the bottom of the tower body 101, which is connected to the liquid outlet channel 110. This makes it easier to collect the coolant that has passed through the second packing 106, and then the coolant is discharged outside the tower body 101 through the liquid outlet channel 110.

[0091] The cooling device 100 provided in this embodiment of the application provides an air outlet channel 109 at the top of the tower body 101 and an air inlet channel 108 at the bottom of the tower body, so that air can enter the tower body 101 from the outside to facilitate subsequent heat exchange between the air and the coolant. Simultaneously, a liquid inlet channel 102 is provided at the top of the tower body. Inside the tower body 101, a first liquid distributor 103, a first packing 104, and a second packing 106 are arranged sequentially from top to bottom. Multiple first water-blocking components 107 and multiple first liquid distribution assemblies 105 are located between the first packing 104 and the second packing 106. An outlet channel 110 is provided at the bottom of the tower body 101. Thus, after the coolant enters the tower body 101 through the liquid inlet channel 102, it undergoes a first heat exchange with the air in the first packing 104. Then, after passing through the first water-blocking components 107 and the first liquid distribution assemblies 105, it is evenly sprayed into the second packing 106, where it undergoes a second heat exchange with the air. The coolant temperature after secondary heat exchange meets the requirements, and therefore can be discharged outside the tower body 101 through the outlet channel 110. Under the same heat dissipation conditions, the cooling device provided in this embodiment can improve the heat dissipation efficiency by 50% and reduce the floor space by 25% compared to a cooling device with only one layer of packing.

[0092] It is understood that the descriptions such as "one item is below another item", "one item is above another item", "top of the tower" and "bottom of the tower" in the embodiments of this application are all based on the state of the tower when it is working normally.

[0093] This application also provides a cooling device, such as... Figure 11 As shown, the cooling device 100 includes: a tower body 101; an air outlet channel 109 and a liquid inlet channel 102 disposed on the top of the tower body 101; and a first liquid distributor 103, a first packing 104, at least one first water baffle 107, at least one first liquid distribution assembly 105, a second packing 106, at least one second liquid distribution assembly, and a third packing 112 disposed inside the tower body 101; and an air inlet channel 108 and a liquid outlet channel 110 disposed at the bottom of the tower body.

[0094] The first liquid distributor 103 is connected to the liquid inlet channel 102; the first packing 104 is located below the first liquid distributor 103; the first water-blocking component 107-1 and the first water-blocking component 107-2 are located below the first packing 104; the first liquid distribution assembly 105-1, the first liquid distribution assembly 105-2 and the first liquid distribution assembly 105-3 are located below the first water-blocking component 107-1 and the first water-blocking component 107-2; the second packing 106 is located below the first liquid distribution assembly 105-1, the first liquid distribution assembly 105-2 and the first liquid distribution assembly 105-3; the second liquid distribution assembly 113-1, the second liquid distribution assembly 113-2 and the second liquid distribution assembly 113-3 are located below the second packing 106; the third packing 112 is located below the second liquid distribution assembly 113-1, the second liquid distribution assembly 113-2 and the second liquid distribution assembly 113-3.

[0095] In this embodiment, an air outlet channel 109 is provided at the top of the tower body 101, and an air inlet channel 108 is provided at the bottom of the tower body, so that air can enter the interior of the tower body 101 from the outside, so as to facilitate heat exchange between the air and the coolant. At the same time, a liquid inlet channel 102 is provided at the top of the tower body, and a first liquid distributor 103, a first packing 104, a second packing 106, and a third packing 112 are arranged sequentially from top to bottom inside the tower body 101. Multiple first water-blocking components 107 and multiple first liquid distribution components 105 are arranged between the first packing 104 and the second packing 106, and multiple second liquid distribution components 113 are arranged between the second packing 106 and the third packing 112. A liquid outlet channel 110 is provided at the bottom of the tower body 101. Thus, after the coolant enters the tower body 101 through the inlet channel 102, it undergoes a first heat exchange with air in the first packing 104. Then, after passing through the first baffle 107 and the first distribution assembly 105, the coolant is evenly sprayed into the second packing 106, where it undergoes a second heat exchange with air. After the second heat exchange, part of the coolant falls into the third packing 112, while the other part is evenly sprayed into the third packing 112 through the second distribution assembly 113. All the coolant undergoes a third heat exchange with air in the third packing 112. After these three heat exchanges, the coolant temperature meets the requirements and can therefore be discharged from the tower body 101 through the outlet channel 110. Thus, by setting up multiple layers of packing, the cooling efficiency of the cooling device is improved.

[0096] In some alternative embodiments, the cooling device 100 further includes at least one second water-blocking element disposed between the second packing 106 and the second liquid distribution assembly 113.

[0097] Specifically, such as Figure 11As shown, the second water-blocking component 114-1 and the second water-blocking component 114-2 are positioned between the second packing 106 and the second liquid distribution assembly 113. Thus, after the second heat exchange, a portion of the coolant falls directly into the third packing 112, while the remaining portion, guided by the second water-blocking components 114-1 and 114-2, also falls into the second liquid distribution assembly 113. The second liquid distribution assembly 113 then evenly sprays all the collected coolant into the third packing 112. All the coolant undergoes a third heat exchange with the air in the third packing 112. After the three heat exchanges, the coolant temperature meets the requirements and can therefore be discharged outside the tower body 101 through the liquid outlet channel 110. Therefore, by placing the second water-blocking component between the second and third packings, the cooling efficiency of the cooling device is improved.

[0098] It is understood that the above examples are merely examples provided to better understand the technical solutions of the embodiments of this application, and are not intended to be the sole limitation on the embodiments of this application. Those skilled in the art can set the number of packing materials inside the tower body 101 according to cooling requirements. For example, four or more layers of packing materials can be set inside the tower body 101, and water-blocking components and liquid distribution components can be set between two adjacent layers of packing materials.

[0099] This application also provides a cooling method, such as... Figure 12 As shown, the cooling method includes: a first liquid distributor spraying liquid flowing into the first liquid distributor into a first packing, so that the liquid exchanges heat with the gas in the first packing and then falls into a second packing and / or a first liquid distribution assembly, wherein the gas flows from one end of the tower body near the second packing to the other end of the tower body near the first packing; the first liquid distribution assembly spraying the collected liquid into the second packing, so that the liquid exchanges heat with the gas in the second packing.

[0100] In this embodiment, the first liquid distributor can uniformly spray liquid into the first packing material. The liquid exchanges heat with the air in the first packing material, and the liquid temperature gradually decreases. After passing through the first packing material, part of the liquid falls directly into the second packing material, and the other part falls into the first liquid distribution assembly. The first liquid distribution assembly can uniformly spray the collected liquid into the second packing material. Thus, the liquid undergoes secondary heat exchange with the air in the second packing material, further reducing its temperature. Therefore, the cooling method provided in this embodiment can improve the uniformity of liquid distribution in the packing material, thereby improving cooling efficiency.

[0101] Since the cooling method provided in this embodiment corresponds to the cooling device provided in the above embodiments, the cooling method provided in this embodiment is also applicable to the previous embodiments, and will not be described in detail in this embodiment.

[0102] In the description of this specification, specific features, structures, materials, or characteristics may be combined in any suitable manner in one or more embodiments or examples.

[0103] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
